HYDEOCABBON BURNER.

Application filed August 13, 1919, Serial No. 317,251.

T 0 all whom it may concern:

Be it known that I, JOSEPH NEEDHAM, a citizen of the United States, and residing at Passaic, in the State of New Jersey, have invented certain new and useful Improvements in Hydrocarbon Burners, of'which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to what are known as hydrocarbon burners, and particularly to devices of this class designed for use in, or in connection with, furnaces and other heat using appliances or apparatus where a high degree of heat is required; and the invention relates particularly to a nozzle or means employed for discharging the hydrocarbon or hydrocarbon mixture into the furnace or other heat using appliance or apparatus; and the object of the invention is to provide an improved device of this class which issimple in construction and use, and which will be efficient in operation and also strong and durable in its resistance to high degrees of heat, and which will not become inoperative or frequently need repair; and with these and other objects in view the invention consists in a device of the class specified, constructed and operating as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which 1 is a longitudinal sectional view of my improved hydrocarbon burner device and indicating the method of its use; and,

Fig. 2 is a sectional detail viewof one end portion of the device shown in Fig. 1

In the drawing, I have. shown a nozzle 7) which comprises a tubular body 6 of any suitable material, preferably material that will resist high degree of heat, and the inner end of the central bore 6 of the body 6 is provided with a flared enlargeient b and the outer end thereof is closed as shown at I)? and passed through the closed end 6 of the tubular body 6 and through said tubular body is a shaft 6 provided at its inner end with a valve head 0, and the outer end of said shaft "is screwthreaded as shown at b and passed through Renewed January 21, 1924.

a stuffing box 6 and provided with a handle 5 The valve head 0 is composed of carborundum, chrome steel, nickel steel or any other material which will resist a high degree of heat and said valve is provided with a collar 0 screwed onto the shaft 6 and connected with the valve head by arms 0 Or any other suitable openwork or spiderwork construction, and the valve head a is provided with a central aperture 0 in connection with which a supplemental valve device 0 is adapted to operate and the stem of the valve 0 extends through the shaft b as clearly shown in Fig. 2.

In the use of the nozzle device, the hydrocarbon mixture is passed into the tubular body 6 through an aperture 72 in the outer end portion thereof and said aperture is threaded to receive a burner head device or mixing device of any kind or class.

With my improved construction, the hydrocarbon mixture may be discharged into the furnace around the main valve 0 or around the supplemental valve 0 or may be discharged through the apertures controlled by both of said valves and it will also be understood that the degree at which these valves are opened, will be regulated by the adjustment thereof to control the supply of the hydrocarbon mixture to the furnaces.

My improved nozzle may .be set into the front wall (Z of a furnace composed of brick or other suitable material as shown in Figl of the drawing, or may be secured to, 0r

in the wall of a furnace, or other gas usingapparatus or appliance constructed in any desired manner and by means of my improvement the discharge of the hydrocarbon mixture into the furnace or other appliance may be controlled and regulated so as to produce the highest possible degree of combustion within the furnace, and the material of which the valves as well as the entire nozzle is composed will besuch' as to resist high degrees of heat in order to materially extend the life of such devices.

One of the chief advantages of my improvement lies in the fact that my improved nozzle device, is totally independent of the burner head, injector or other means employed for supplying the hydrocarbon or hydrocarbon mixture; afurther advantage being in the simplicity of the device, its

comparative cheapness, its practical indestructibility and the far-t that a new nozzle may be substituted for an old one When necessary, at comparatively slight loss of time and expense.

Having fully described my invention,.

What I claim as new and by Letters Patent, is

A hydrocarbon burner device provided 10 with a fuel port or passage, means whereby a hydrocarbon mixture may be supplied to one end portion of said port or passage and discharged from the other end thereof, a valve device adjustable reiatively to the dis- 15 charge end said port or passage and prodesire to secure JQSEPH NEEDHAM.
